Excited analog states of _Λ¹²C and the alpha particle model

Abstract

The idea that _Λ¹²C^* is a strangeness analog state is examined using the alpha particle model. Volkov, Gillet, and Brink-Boeker potentials are used for the nucleon-nucleon and lambda-nucleon interactions, to calculate the binding energies of ¹²C and _Λ¹²C^*. ¹²C is described by an equilateral triangle. When an allowance is made for the exchange character of the potentials used, the required potential strengths seem to be consistent with those obtained from low energy and light hypernuclear data, thus supporting the idea of a strangeness analog state. Nuclear Structure _Λ¹²C^*, binding energy calculated assuming strangeness analog state in alpha particle model.
