Popis:	X-rays originating from a series of the cascades after electron capture into highly excited Rydberg states have been observed from low energy, highly charged Kr q + ions ( q =27–36) colliding with neutral Ar atoms. The intensity ratio between L ( n =3→2) X-rays and the sum of M X-rays ( n =4→3, n =5→3, n =6→3, etc.) is drastically changed from Kr 27+ to Kr 28+ and constant for higher ion charge states ( q =29–36). This feature can be understood to be due to the metastable states formed during cascades after electron capture into Kr 27+ ions. This is also supported by time-dependent population calculations.
