Abstract

Precise measurements of the isotope shift for muonic

K

transitions are reported for

{Si}^{28, 29, 30}

,

K^{40, 41}

,

{Ca}^{40, 42, 44, 48}

,

{Fe}^{54, 56, 57}

,

{Ni}^{58, 60, 61, 62}

,

{Cu}^{63, 65}

,

{Sr}^{86, 87, 88}

,

{Zr}^{90, 92}

, and

{Sn}^{116, 117, 118, 119, 120, 122}

. The shifts

{Ca}^{40}

-

{Ca}^{44}

and

{Ca}^{40}

-

{Ca}^{48}

are of special interest, as they confirm the conclusions from electron scattering. The shifts

{Sr}^{86}

-

{Sr}^{87}

and

{Sr}^{86}

-

{Sr}^{88}

are found to be negative, indicating that the heavier isotope has a smaller charge radius.
