Hyperspherical formalism for the photoeffect of the alpha particle

Abstract

In this work we employ the hyperspherical harmonics formalism to calculate the moments of the photoeffect of the alpha particle. The grand orbital quantum number is increased until well-converged results are obtained. The adiabatic approximation is used to solve the coupled differential equations. The calculations are performed for a central N-N potential with Serber exchange. Lastly, the moments are inverted to obtain the photodisintegration cross section. Comparisons with experimental observations are presented. © 1985 The American Physical Society.
