We have explored a novel approach of electron‐impact postionization involving the use of a focused low‐energy electron beam directed at the flux of sputtered particles in very close proximity to the sample surface [‘‘matched’’ e‐beam sp

A single closed‐form expression is obtained for the probability amplitude ψ(x,t) for a harmonic oscillator whose initial state ψ(x,0) has a minimum value for the uncertainty product of position x and momentum p, Δx Δp=ℏ/2. This form describes

Two examples are given of the use of cumulant expansions for systems of particles with hard‐core two‐body interactions. One of these, in classical statistical mechanics, is shown to lead to virial coefficients. An analogous procedure in quantum m

A high-energy neutron detector has been developed using a semiconductor diode fabricated from bulk gallium arsenide wafers with a polyethylene neutron converter layer. Typical thickness of the diode layer is 250 to 300 μm with bias voltages of 30 to

A model for the symmetric three-body decay of a 12C- alpha -12C configuration is presented. It is applied to the decay of the ECM=19.7 MeV 14+ resonance observed in 16O+12C-induced reactions. The comparison with data from a 12C-12C coincidence experi

A simple approximate method using the Heisenberg uncertainty relation and a variational principle is used to obtain energy eigenvalues and corresponding system sizes for a large class of bound quantum systems. Results obtained with this method are co

The 11.1 MeV 5- resonance in the 12C+16O reaction is remeasured and the position of the resonance is determined to be Ex(28Si)=(27.881+or-0.022) MeV. A kinematically complete study of the 12C(16O, alpha 12C)12C reaction into this resonance is carried
