Introduction
Introduction

  • Superdeformed states in light systems:

    40Ca(8p-8h); 36Ar(4p-4h); 40Ar (“4p-4h”)

  • Recently, 42Ca(4p-4h? 8p-8h?).

  • Rotational band in 42Ca:

    Cranked HFB calculation

  • Superdeformation?

  • 8p-”6”h configuration [4p-4h x (2+2)p-2h ]

  • Backbendingdue to g9/2 at I=20.

  • Qtand high-spin experiments.
