INELASTIC ELECTRON SCATTERING FROM 3He AND 4He IN THE THRESHOLD REGION AT HIGH MOMENTUM
نویسندگان
چکیده
The cross section for inclusive inelastic electron scattering from the helium isotopes has been measured at momentum transfers squared of 0.8zQ2<5.0 (GeV/c)2 for 3He and 0.8LQ212.4 (GeV/c)2 for 4He. The data were taken at 8O and cover the range 0.6<x<l, where x = Q2/2MHeV, which includes the elastic peak, nuclear breakup threshold, the high momentum tail of the quasi elastic scattering, and pion production. The structure function, VW,, derived from the data is approaching a scaling limit at high Q2. It can be factored into a product of functions of Q2 and of x as predicted by some models.

Dissipation mechanisms near the superfluid 3He transition in aerogel.
We have investigated the dissipation (Q-1) using the torsion pendulum technique for pure 3He and 3He-4He mixtures in silica aerogel near the 3He superfluid transition (T(c)) in aerogel. With pure 3He the Q-1 decreases at the onset of superfluidity. When phase separated 3He-4He mixtures are introduced into the aerogel, the Q-1 does not decrease as rapidly and eventually increases for the highest...
متن کاملElectrodisintegration of Few Body Systems at Slac and the Y Scaling Approach
It is proposed that extraction of the scaling function F(y) from the transverse and longitudinal response functions in inclusive quasi-elastic electron scattering from 3He and 4He is a powerful method to either study the validity regime of the impulse approximation by allowing the access to the high nucleon momentum components in these nuclei, or the electromagnetic properties of bound nucleons.
متن کاملMicroscopic approach to the response of 3He-4He mixtures.
Correlated-basis-function perturbation theory is used to evaluate the zero-temperature response S(q ,v) of He-He mixtures for inelastic neutron scattering, at momentum transfers q ranging from 1.1 to 1.8 Å. We adopt a Jastrow correlated ground state and a basis of correlated particle-hole and phonon states. We insert correlated one-particle–one-hole and oneand two-phonon states to compute the s...
متن کاملAccurate measurement of atmospheric helium isotopes.
We have developed an analytical system to measure atmospheric 3He/4He ratios precisely by using a static vacuum operation mass spectrometer and an ultrahigh-vacuum purification line. After purification of the sample, helium was introduced into the mass spectrometer. Ion beams of 3He and 4He were measured at the same time by a double collector system. A resolving power of about 700 at the 5% lev...
متن کاملSmall ηN scattering lengths favour ηd and ηα states
Unstable states of the eta meson and the 3He nucleus predicted using the time delay method were found to be in agreement with a recent claim of η-mesic 3He states made by the TAPS collaboration. Here, we extend this method to a speculative study of the unstable states occurring in the ηd and η4He elastic scattering. The T -matrix for η 4He scattering is evaluated within the Finite Rank Approxim...
