It will not change. It doubles.

Work Step by Step

Her angular momentum does not change because no net external torque acts on her. Angular momentum is the product of her rotational inertia and rotational velocity, so if her rotational inertia is halved, her spin rate doubles to keep the product constant. This is discussed on page 151, and shown in Figure 8.52.
