On the Q-value of the tritium β-decay
– We report here the atomic masses of H and He determined by using the Penning trap mass spectrometer Smiletrap. The measurements are based on cyclotron frequency determinations of H and He using H+2 ions as mass reference. The mass values for H and He are 3.016 049 278 7(25) u and 3.016 029 321 7(26) u, respectively. From these masses a new Q-value of the tritium β-decay was derived resulting ...
متن کاملThe Q-Exponential Decay of Subjective Probability for Future Reward: A Psychophysical Time Approach
This study experimentally examined why subjective probability for delayed reward decays non-exponentially (“hyperbolically”, i.e., q ˂ 1 in the q-exponential discount function) in humans. Our results indicate that nonlinear psychophysical time causes hyperbolic time-decay of subjective probability for delayed reward. Implications for econophysics and neuroeconomics are discussed.
متن کاملDecay Probability Ratio of Pentaquark Θ State
The pentaquark state of Θ+(uudds) has been observed to decay with two decay modes: Θ+ → nK+ and Θ+ → pK0. The decay probability ratio of the two decay modes is studied with general symmetry consideration of isospin, spin, and parity. We arrive at a result of the ratio Γ(Θ →nK) Γ(Θ+→pK0) = (α−β) 2 (α+β)2 (1 k2 )2L+1, which is valid for the Θ+ state to be a pure isoscalar or isovector state, or a...
متن کاملDecay of (p,q)-Fourier coefficients.
We show that essentially the speed of decay of the Fourier sine coefficients of a function in a Lebesgue space is comparable to that of the corresponding coefficients with respect to the basis formed by the generalized sine functions sin p,q .
متن کاملProbability Value Library 1
Hidden Markov models (HMMs) and other time series models assign probabilities to long sequences of events. Avoiding underrow is arguably the central diiculty in calculating the probability of such sequences. This technical report presents an elegant and eecient C library for representing and manipulating probability values without underrow. Use of the library results in simpler code whose execu...
